Stratification variables: recruitment centre (7 centers), fall during previous 12 months (yes/no), gender, and age (70 - 84 and 85+). Even balance among those who fell or did not fall during the last year will be enforced at each of the 7 recruitment centers. Gender and age distribution will be monitored within each recruitment centre with the DO-HEALTH randomization software. If gross imbalance (less than 30% of participants in a stratum) is detected within a centre, recruitment strategies for the centre will be adapted to boost recruitment of participants of underrepresented category.
